The Indian trading house Adani Resources Ltd. has just reached an agreement with the Queensland government on royalty payments for the Carmichael coal mine, which the company is considering building in northeastern Australia. As one of the largest thermal coal mines in the world, it would exert a country-sized impact on global carbon emissions during its 60-year life. As the company decides whether to go ahead, it will need to keep in mind three relevant energy trends.
First, Australian coal remains cheaper than natural gas – but not hugely so. Since 2011, coal has been as high as $5.38 per million British thermal units and gas as high as $13.96/MMBtu. However, since 2014, gas has fallen below coal’s peak prices. Thanks to U.S. exports, the world may soon be flooded with natural gas, and that means gas prices aren’t likely to be spiking upward.
Asian Gas Plunges, But Coal Is Still Cheaper
Second, in the past year, the cost of solar generation in India has fallen by more than half. The country’s competitive auctions for solar power have pushed prices below 2.5 rupees ($0.04) per kilowatt-hour. While much experience with energy auctions has taught Bloomberg New Energy Finance to be skeptical of ultra-low bids, the trend is important. Solar is cheap and getting cheaper, and at a certain point it becomes hard to turn down as a marginal unit of new power generation.
Down by Half
The third trend has to do with the broader energy market in India. Solar at 4 cents undercuts the cost of other major generation sources. By BNEF’s calculations of the so-called levelized cost of energy 1 , solar has become significantly cheaper than new gas and coal-fired power. (Oh, and wind is also slightly cheaper than coal.)
Solar Prices Lowest
As my colleagues say in a research note, “Cheap and plentiful PV could lead to a strategic rethink on how India meets its future demand for electricity.” And analysts aren’t the only ones who think so. Indian power market players also say that solar’s cost trend may limit the expansion of conventional power generation.
To be sure, coal-fired power is in India to stay. It will probably even increase in absolute terms as electrification expands with the economy. At the same time, India’s domestic coal production is increasing, pushing its prices down about 10 percent lower than those of Australian imports. This differential might not be an issue for Adani Enterprises, which intends to export only to its own power projects on the coasts, where imports are still cheaper than domestic supply. But new infrastructure connecting inland Indian mines to the coasts could change that math during the lifetime of the Carmichael mine.
Imported coal today faces cost competition from natural gas, renewables and domestically mined coal. It’s a dynamic market that presents challenges for the Adani board as it decides whether to invest in a 60-year asset.
